Genus
Common name: Sea Cucumber
Scientific name: Pearsonothuria
Pearsonothuria is a genus of sea cucumbers known for its striking coloration and patterns. The most notable species within this genus is Pearsonothuria graeffei, which is often found in reef aquariums. These sea cucumbers are known for their beneficial role in the sand bed as they sift through the substrate, aiding in detritus removal and nutrient cycling. They are nocturnal and require a well-established tank with plenty of live sand and rock for foraging. Their diet consists of organic matter and detritus, but they may also accept supplemental feeding.
